Hi Eric,
A pic of the back would be nice since seeing the presence of an "I" below the balance wheel would indicate if your Cal 11 has been factory modified to incorporate improvements used in the latter Cal 12. Does your watch have "Chronomatic" above the Heuer log on the dial? That would indicate the very earliest version of the automatic Autavia (and make it very rare).
